Abstract

The present invention provides novel methods for classifying, diagnosing and/or treating a group of human and veterinary ailments involving endogenous opioid concentrations. Also provided is a novel use for an existing class of compounds, the opioids, to treat opiopathic ailments, particularly paresis/paralysis, pseudo-atrophy and/or opiopathic pain, and in the manufacture of pharmaceutical and veterinary formulations therefor. The invention also relates to neuropathic, polyneuropathic, neurologic and neurogenic ailments typically characterized by paresis/paralysis. These ailments can involve an abnormal concentration of one or more endogenous opioids, or the blockade, underexpression or overexpression of one or more opioid receptors. In that regard, the invention encompasses therapeutic uses, methods and compositions employing opiates and/or their receptors. In particular, the invention relates to certain laboratory testing methods, clinical testing methods, research and development methods, business methods, methods of treatment, novel therapeutic uses, and human and veterinary pharmaceutical dosage forms, dosing regimens and formulations, especially those pertaining to opiopathy (particularly hypo-opiopathy).

Claims

1. A method for treating an opiopathy, which method comprises administering to a subject in need thereof an effective amount of an anti-opiopathic active agent.

2. The method of claim 1 comprising a treatment for an opiopathy involving an abnormal level of an endogenous opioid.

3. The method of claim 1 comprising a treatment for hypo-opiopathy characterized by deficiency of an endogenous opioid, wherein said anti-opiopathic active agent is an exogenous equivalent or replacement for said endogenous opioid.

4. The method of claim 1 comprising a treatment for hypo-opiopathy characterized by deficiency of an endogenous opioid, wherein said anti-opiopathic active agent has substantially the same opioid receptor type specificity as said endogenous opioid.

5. The method of claim 1 wherein said opiopathy involves one or more of:

paresis/paralysis, pseudo-atrophy, opiopathic pain, immune surveillance, tumor surveillance, behavior modulation, neuromuscular modulation or neuroendocrine modulation;

paresis/paralysis, pseudo-atrophy, opiopathic pain, immune surveillance, tumor surveillance or neuroendocrine modulation;

paresis/paralysis, pseudo-atrophy or opiopathic pain;

paresis/paralysis or pseudo-atrophy;

Upper Respiratory Obstructive Syndrome or Opioid-responsive Polyneuropathic Syndrome;

lingual, pharyngeal, laryngeal, esophageal, urinary bladder sphincter, lumbar and lumbo-sacral spine, and pelvis and pelvic limb paresis/paralysis;

opioid-responsive neurogenic urinary bladder sphincter paresis/paralysis;

cardiomyopathy, centrally mediated depression, congestive heart failure, or paralytic intestinal ileus;

Multiple Autonomic Nervous System Dysfunction, Multiple Sclerosis, Myasthenia Gravis, Parkinson'"'"'s Disease, Post-Polio Syndrome or ALS; and

Multiple Autonomic Nervous System Dysfunction, Multiple Sclerosis, Parkinson'"'"'s Disease, Post-Polio Syndrome or ALS.

6. The method of claim 1 wherein said opiopathy involves one or more of:

pseudo-atrophy, where the treatment results in a rapid return of muscle function and tone as compared to treatment of atrophy;

Multiple Sclerosis, Parkinson'"'"'s Disease or ALS, where the anti-opiopathic active agent includes an opiate agonist and an opioid antagonist;

Multiple Sclerosis, where the anti-opiopathic active agent is administered in an amount sufficient to normalize neuronal and neuromuscular transmission, and down-regulate IL-12;

Multiple Sclerosis, where the anti-opiopathic active agent is hydrocodone or oxycodone, administered in an amount sufficient to treat emotional incontinence;

Multiple Sclerosis, where the anti-opiopathic active agent is hydrocodone, administered in an amount sufficient to treat emotional incontinence; and

Myasthenia Gravis, where the anti-opiopathic active agent is a very low dose of an immediate release formulation.

7. The method of claim 1 wherein said subject is a mammal.

8. The method of claim 7 wherein said subject is a human or a dog.

9. The method of claim 1 wherein said anti-opiopathic active agent is morphine, codeine, thebaine, papaverine, noscapine, hydromorphone, metapon, oxymorphone, levorphanol, hydrocodone, oxycodone, tramadol, nalorphine, naloxone, naltrexone, meperidine, a meperidine congener, methadone, a methadone congener, levorphanol, a levorphanol congener, phenazocine, propoxyphene, ethoheptazine, or a pharmaceutically or veterinarily acceptable salt thereof.

10. The method of claim 9 wherein said anti-opiopathic active agent is morphine, codeine, hydromorphone, hydrocodone, oxycodone, naloxone, naltrexone or a pharmaceutically or veterinarily acceptable salt thereof.

11. The method of claim 10 wherein said anti-opiopathic active agent is morphine, oxycodone, or a pharmaceutically or veterinarily acceptable salt thereof.

12. The method of claim 1, comprising administering an opioid agonist and an opioid antagonist.

13. The method of claim 12 wherein said opioid agonist is morphine, oxycodone, tramadol or hydrocodone and said opioid antagonist is naltrexone.

14. A pharmaceutical or veterinary formulation comprising an opiate, a pharmaceutically or veterinarily accepted excipient, and a detractant.

15. The formulation of claim 14 wherein said detractant is an odor, flavor, texture or other ingredient that while palatable to a non-human mammal is unacceptable to a human being.

16. The formulation of claim 15 manufactured in a dosage form that is unsuitable for human consumption.

17. A pharmaceutical or veterinary product comprising a formulation according to claim 14 having outer packaging prominently labeled to highlight the presence of said detractant as a warning against human consumption or diversion.

18. A pharmaceutical or veterinary product for dose escalation, comprising:

(a) a pharmaceutical or veterinary formulation of claim 14 having said opiate at a starting dosage level, in a quantity sufficient for administration over an initial period of time,

(b) a second such formulation having said opiate at an incrementally higher dosage level wherein the dosage is increased by a factor ranging from about 1.25 to 2.0, in a quantity sufficient for administration over a subsequent period of time, and

(c) instructions for administration of the formulation and determination of therapeutically effective and maximum tolerated doses.

19. A method for treating an ailment of the group:

paresis/paralysis, pseudo-atrophy, Upper Respiratory Obstructive Syndrome, Opioid-responsive Polyneuropathic Syndrome, cardiomyopathy, centrally mediated depression, congestive heart failure, paralytic intestinal ileus, Multiple Autonomic Nervous System Dysfunction, Multiple Sclerosis, Myasthenia Gravis, Parkinson'"'"'s Disease, Post-Polio Syndrome or ALS, which method comprises administering to a subject in need thereof an effective amount of an opiate.
